Emulsion Stability of Heavy Oil with Surfactants and Nanoparticles
The recovered crude oil is often in form of an emulsion and the recovery is cut off when water to oil ratio exceeds a certain amount. The emulsions vary from water-in-oil to oil-in-water and the step that follows is to coalesce droplets to get two ...

Elution of viruses by ionic and nonionic surfactants [PDF]
The ionic and nonionic surfactants sodium dodecyl sulfate and Triton X-100, respectively, eluted two viruses, phi X174 and PRD1, which were adsorbed to the ionic and nonionic binding membranes cationic polysulfone and nitrocellulose, respectively. Results indicated that complete elution was readily achieved only when combinations of surfactants and ...

Nonionic Surfactant Sorption onto Soil
Experiments in batch soil/aqueous systems were conducted to evaluate the sorption onto soil of four nonionic surfactants. At bulk solution surfactant concentration less than the respective critical micelle (aggregate) concentration (CMC or CAC), sorption

Nonionic Surfactants in Paper Electrophoresis
Abstract 1. A modification of the usual paper electrophoretic procedure has been made by including in the buffer medium 0.05 per cent of certain alkylphenyl ethers of polyethylene glycol. 2. This modified procedure yields electrophoretic patterns of blood serum proteins that may be subdivided into 12 fractions— albumin, α1-
